Backtrace of plasmashell crash

SUMMARY
Plasma Shell and KWin started to crash after installing latest Neon updates. I fixed the KWin crash by changing to OpenGL 2.0 in compositor settings, which now allows me to manually restart it.

STEPS TO REPRODUCE
1. Login to Plasma

OBSERVED RESULT
The layout is normal and visible for a few seconds and then plasmashell and kwin crashes.

EXPECTED RESULT
Plasmashell and kwin not crashing.

SOFTWARE/OS VERSIONS
Linux: KDE Neon 5.18
KDE Plasma Version: 5.18.0
KDE Frameworks Version: 5.67.0
Qt Version: 5.13.2

Crashing in Decoration::Applet::PreviewClient::requestShowToolTip()

Are you using a non-standard window decoration theme?

Why was this moved to kwin?

Comment 3 David Edmundson 2020-02-16 23:07:03 UTC

Crash is in "applet window buttons" which afaik isn't from KDE.

I suspect you need to rebuild it after an abi break.
